The P2710 DTC gets saved in the ECU when the computer notices an intermittent problem with the solenoid labeled ‘F’. This electromechanical device is used to channel pressurized hydraulic fluid inside the transmission, for the purposes of actuating a gear change. If the computer cannot control it, drivability issues will occur.
How Serious is the Code?
A P2708 diagnostic trouble code means that one of the shift solenoids may intermittently not work. This will lead to a number of transmission problems including, slipping, delayed shifts and even engine stalling. Needless to say, this can affect the performance and safety of your vehicle.
Symptoms of a P2710 include:
- Unusually harsh shifts
- Delayed shifts
- Transmission overheating
- Poor performance
- Limp mode
- Low transmission fluid level
- Dirty transmission fluid/filter
- Damaged wiring
- Corroded connectors
- Blocked passages inside the valve body
- Failed shift solenoid
- Programming issues with the ECU/TCM
How to Diagnose the Code?
When diagnosing a P2710 OBDII diagnostic trouble code, a mechanic should first check the level and condition of the transmission fluid. They should also check for any manufacturer TSBs related to the issue. The wiring and connectors on the transmission wiring harness should also be carefully inspected for signs of a frayed/shorted wire or corroded connector. If no issues are found by this point, further diagnostic steps will have to be taken to determine if there is an issue with one of the solenoids or the valve body.
What Repairs Will Fix P2710?
- Change the transmission fluid/filter
- Repair any damaged wiring/connectors
- Update TCM programming
- Replace shift solenoid
